The device has an air guidance assembly (1) integrated in a water plug (9) i.e. over ground water plug, for automatic air discharge in an atmosphere by the water plug of air flowing from a water supply network (97). The assembly is built into upper and lower riser pipes (92, 93) of the water plug. The assembly includes a chamber with a chamber end connected with a flow passage that is extended by a disk of the water plug. An air valve is arranged at another chamber end. The assembly is connected with a valve rod (8). A float assembly is movably guided into the chamber between the ends. |
